在Ubuntu 14.04上刮擦

Question

I"m getting these error when i create a scrapy project. I already went through all the google links and it just wont work out for me on ubuntu 14.04

    Traceback (most recent call last):
  File "/usr/local/bin/scrapy", line 11, in <module>
    sys.exit(execute())
  File "/usr/local/lib/python2.7/dist-packages/scrapy/cmdline.py", line 122, in execute
    cmds = _get_commands_dict(settings, inproject)

ImportError: No module named cryptography.hazmat.bindings.openssl.binding

Some say do pip install pyOpenSSL==0.13 i get the following

   OpenSSL/crypto/x509.h:17:25: fatal error: openssl/ssl.h: No such file or directory

 #include <openssl/ssl.h>

                         ^

compilation terminated.

error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

您需要安装libssl-dev软件包：

sudo apt-get install libssl-dev
